Optical DO monitoring

Thermo Scientific – AquaSensors has introduced a new generation of online optical dissolved oxygen sensor technology. The RDO Pro DO Sensor represents the latest in luminescent dissolved oxygen technology for wastewater monitoring. In addition to no membranes, no conditioning and fast start-up, the technology now also offers improved resistance to both photo bleaching and abrasion by aggressive process media. The instruments employ “smart sensor” technology and complement AquaSensors full range of online liquid analytical sensors including the patented DataStick™ “smart” and AnalogPlus™ series sensors for pH/ORP, conductivity, dissolved oxygen, ozone, free chlorine, turbidity and suspended solids.

DO sensor

With a fluorescence quenching (FQ) sensing element, the Triton DO8 Dissolved Oxygen Sensor from Electro-Chemical Devices (ECD) delivers accurate DO measurement with greatly reduced maintenance requirements. The sensor is designed with precision FQ optical technology coupled with intelligent microprocessor-based electronics. The self-monitoring device stores calibration data within the sensor, which minimizes maintenance over long service intervals while providing stable DO measurement.

Reagent sets

Hach has added three new TNTplus reagent sets: Copper, High-Range (HR) Nitrite, and Mercury-Free Chemical Oxygen Demand (COD) to its range of parameters. Ideal for wastewater (copper, HR nitrite and COD), drinking water (copper) and industrial applications (monitor/control copper-based alloys, HR nitrite as an oxygen scavenger in closed cooling systems), these new products help make laboratory testing with spectrophotometers easier and more accurate.

Particle analysis software

Laboratory instrumentation firm Fluid Imaging Technologies has introduced VisualSpreadsheet© V2.0, an interactive particle image analysis software program that enables operators to apply filter parameters during data acquisition to detect and identify particles and cells of interest immediately and in real time while a sample is running rather than waiting until the entire sample has been processed before seeing any results. Developed as a companion to the company’s FlowCAM® automated particle analysis system, the software allows lab technicians, water quality engineers, QA/QC managers and others to build filters that automatically segment and categorize the population of particle and cell images detected based on dozens of measurement parameters including shape, aspect ratio, ESD, perimeter, elongation, compactness, intensity and transparency.

Turbidimeter

GF Piping Systems has added the new Signet 4150 Turbidimeter to its line of analytical instrumentation. The new meter is compliant to U.S. EPA 180.1, making it ideal for both municipal and industrial applications. With its integral pressure regulator, it features easy one-unit installation and setup. Typical uses include monitoring for potable water distribution, raw or filtered water, wastewater effluent, and aquatic life support. The unit’s replaceable desiccant pack assures a stable environment for accurate measurement and a built-in backpressure valve can be adjusted to eliminate bubbles that may cause reading errors.

Portable turbidimeter

The new TB200™ Portable Turbidimeter from Orbeco-Hellige allows for turbidity measurement in the field and in the laboratory. It uses a “white light” source and 90° detection, and meets the USEPA specifications for turbidity measurement (EPA Standard 180.1). The meter features an auto-ranging function that automatically selects the correct turbidity range for a sample. Calibration is simple with the included calibration standards. An efficient microcircuit design allows the instrument to yield 5,000 tests on 4-AA alkaline batteries with an estimated 7-10 year bulb life.
